Emerson Rosemount 8800 Vortex flowmeters improve process efficiency, productivity, plant safety.


BillerudKorsnäs is a world-leading manufacturer of strong primary fiber-based packaging material in Sweden. The mill had previously used a magnetic flow meter to measure the flow of white liquor used in a pulp digester. This technology is frequently used for this type of application, however it was unsuccessful in this case because the flowmeter was occasionally subjected to a significant vacuum that partially collapsed the liner. This caused the magmeter to read a higher flow rate, resulting in too little alkali input which reduced digester performance. As the process could not be stopped outside the scheduled shutdown period, it was not possible to replace the meter immediately. The company was looking for a reliable solution to overcome these challenges and turned to Emerson. They installed the Rosemount 8800 Vortex flowmeter which are not typically considered for this application, as the fluid contains solids and fibers that would clog the crevices and ports common to traditional vortex flowmeters, impacting the meter performance. However, the unique design of the Rosemount 8800 Vortex eliminates crevices and ports and thus eliminates the risk of clogging. In addition, the 8800 is balanced so it is not affected by vibrations in the pipes that are typical in mill applications. The resulting flow measurement is accurate, stable and reliable. Finally the accurate flow measurements from Rosemount 8800 Vortex flowmeters translated to more consistent pulp quality and a lower cost per tonne of pulp saving the company millions of dollars. The mill also reduced maintenance costs considerably by eliminating the need to remove and clean the failed flowmeter. Thus BillerudKorsnäs achieved improved process efficiency, productivity and better safety for their process plant.DOWNLOAD VALVE SOLUTIONS APP. WANT TO PROMOTE YOUR PRODUCT? FEEDBACK @anand_rkrishnan
